Using a VTL Password 349
■
The prepend command adds the IP address and system password of
the destination system to the extension dialed by a user. In Figure 26 ,
the IP address for Atlanta is 192.168.25.100 and the password is
ATLPassW. For Dallas, the IP address is 192.168.35.100 and the
password is DALPWord. In the dial plan, you use an asterisk (*) instead
of a period (.) to separate fields within the IP address and to separate
the IP address from the destination extension.
To place a hop-off call to 555-1212 in area code 903 through the Atlanta
system, a user on a remote system would dial 72919035551212. The 72
code sets up a VTL connection to Atlanta that incudes the Atlanta
system’s VTL password, and the remaining digits are used to dial the
number (9 accesses an outside line to obtain dial tone from the local
carrier, 1 accesses the long-distance carrier, and the remaining digits
specify the long-distance number).
If the same user used site code 62 to place a call to the Atlanta office,
only toll-free, emergency, and internal call would be allowed.
Toll Calls Without a
VTL Password
If a local user has configured his telephone to forward calls to a
long-distance number, then an incoming VTL call to that telephone does
not need to supply the local system’s VTL password in order for the call to
be forwarded.
Music On Hold If two users are talking on a VTL connection, and the first user places the
call on hold, the second user hears Music On Hold only if his local system
is configured to play it.
